摘要采用CsCl/KCl自熔剂法合成了Cs-NbS 2（CsxNbS 2）单晶。在起始材料中添加金属镉后，Cs x NbS 2单晶的尺寸和Cs含量增加。当原料中Cd/Nb为10- 30at%时，可得到尺寸为1-2 mm、厚度为10-100 μm的Cs × NbS_2（x ≤ 0.3）片状单晶。这些Cs_xNbS_2单晶的超导转变温度为1.65K。
Abstract Single crystals of Cs-intercalated NbS2 (Cs x NbS2) were synthesized using a CsCl/KCl self-flux. The size and Cs content of Cs x NbS2 single crystals increased upon adding Cd metal into the starting materials. When 10–30 at% of Cd per Nb was provided in the starting materials, plate-like Cs x NbS2 (x ∼ 0.3) single crystals with 1–2 mm in size and 10–100 μm in thickness were obtained. The superconducting transition temperature of these Cs x NbS2 single crystals was 1.65 K.
